| Abstract/Contents: | Discusses the biology, physical characteristics, and growth pattern of yellow nutsedge (Cyperus esculentus L.). "Traditionally, the herbicides MSMA (sold under numerous trade names) and bentazon (tradename Basagran) have been used to suppress yellow nutsedge. These are contact herbicides, and although foliage may die, tubers are not directly affected. Furthermore, both MSMA and bentazon may cause slight to severe chlorosis to some turfgrasses after application. A new herbicide, halosulfuron-methyl (HM, sold under the trade name Manage by Monsanto), should be available in 1995 for use on yellow nutsedge in turf. Unlike MSMA and bentazon, HM has some systemic activity. Research was done in 1992 and 1993 in Kansas and Maryland (with the cooperation of Dr. Peter Dernoeden) to evaluate HM safety on cool-season turf and efficacy on yellow nutsedge at several application rates. Bentazon was included for comparison. Kentucky bluegrass (Poa pratensis L.) and creeping bentgrass (Agrostis palustris Huds.) exhibited good tolerance to HM and bentazon. Perennial ryegrass (Lolium perenne L.) treated with bentazon (1120 or 1680 g/ha) exhibited slight to severe injury up to five weeks after application. Halosulfuron-methyl (>70 g/ha) reduced perennial ryegrass quality in Maryland below an acceptable level for about one week after HM treatment. Yellow nutsedge topkill in Kansas by HM (70 g/ha) ranged from 52 to 97%. A single HM application (35, 70, or 140 g/ha) provided >97% yellow nutsedge topkill in Maryland. Yellow nutsedge topkill provided by bentazon was generally inferior to that provided by HM. Thus, a new weapon in the arsenal to combat yellow nutsedge will soon be available." |
